The theoretical model for apparent viscosity of polymer melt under an superimposed vibration was set up independent of any existing constitutive equations. Meanwhile, the calculating steps for previously apparent viscosity were established by making use of novel rheological measurement equipment that was ...
Sutherland’s formula for calculating the viscosity of a gas at a specified gas temperature is shown below along with an explanation of the parameters in the equation. The parameters in Sutherland’s formula are as follows: To = reference temperature, K μo = viscosity of the gas at temperatu...
